A summarizer for long texts with adjustable length is a tool that condenses articles, reports, or documents into shorter versions while preserving the main ideas and structure. It lets users set how brief or detailed they want the summary to be—ranging from a quick overview to a more in‑depth digest—so the output matches different reading needs. This kind of tool helps students, professionals, and researchers quickly grasp key points, compare multiple sources, and manage information overload without reading every document in full.
